Oshima debuts revolutionary bulker design

Oshima Shipbuilding, widely held to be among the finest bulker builders in the world, has debuted a new ultramax design, which it claims has a 50% reduction in EEDI.

The Oshima Ultramax 2030 will be LNG-fuelled, featuring an engine from Wärtsilä. As well as an optimised hull shape and a hard sail, the design from the Japanese yard offers ultra-low emissions in port, by using solar panels and a battery to cover the hotel load during waiting times and port operations.

The design was conceived in association with class society DNV GL and is the start of a collaboration between the two, aimed at coming up with zero emission ship designs.

“To help the industry meet the ambitious GHG reduction targets set by the IMO, the industry needs to come together to advance ship design, taking advantage of both existing and new technologies,” commented Trond Hodne, director of sales and marketing at DNV GL. “This partnership shows how much can come of this approach. The design halves the EEDI of comparable vessels and sets a new standard for low emission bulk carriers.”
